Robin Williams was born on July 21, 1951 in Chicago, the great-great-grandson of Mississippi Governor and Senator Anselm J. McLaurin. His mother Laura was a former model from New Orleans while his father Robert was a senior executive for the Ford Motor Company. After briefly pursuing a career in politics, he enrolled at the Julliard School in 1973, where he was one of only 20 students accepted into the freshman class, and one of only two to be accepted into the advanced program, alongside Christopher Reeve. He left the school in 1976.

After appearing on Laugh-In, The Richard Pryor Show and Eight Is Enough in 1977, the actor was cast as an alien named Mork in a 1978 episode of Happy Days, which was so popular it received its own spin-off, Mork & Mindy, which ran from 1978 to 1982. He also began to expand his stand-up comedy career with three HBO specials that aired in 1978, 1982 and 1986. He also hosted The Academy Awards in 1986, just before his feature film career began to take off.

The actor starred in the 1987 hit Good Morning, Vietnam, which earned him his first Oscar nomination. He was also nominated for Dead Poets Society and The Fisher King before his first Oscar win for Good Will Hunting in 1997. Among his other big-screen hits are Hook, Aladdin, Mrs. Doubtfire, Jumanji, Patch Adams, Night at the Museum, Night at the Museum: Battle of the Smithsonian and this year's Night at the Museum: Secret of the Tomb, where he reprises his role from the first two adventures as Teddy Roosevelt.
